2036038 - Shared workers should persist between navigations

Press navigate a bunch of times. Note that the number from the worker is the same each time. This is because it's the same worker instance. This is expected behaviour.

Spec: https://html.spec.whatwg.org/multipage/workers.html#between-loads-shared-worker-timeout

However, here's the same demo, but with an unload handler, designed to prevent bfcache: https://random-stuff.jakearchibald.com/shared-worker-navigation/?no-bfcache (make sure you don't have other tabs open to the site)

In this case, the number is different each time, because the worker is being destroyed and recreated.
